Are you sure this is done in the MTA phase and not in the MDA oder MSA
phase? qmail e.g. also checks Delivered-To fields but it is done in the
MDA phase by qmail-local (i.e. during the delivery and this is also
where they get added). And qmail also adds Date and other fields but
it is done in the "sendmail" substitute that is the queue injector for non
SMTP/MSA connections.
